Tool milling machines are automated machine tools used to machine workpieces by removing material with rotating tools. They are usually equipped with a table on which the workpiece is mounted and a milling head that holds the tool and moves it against the workpiece. Tool milling machines can be used to perform a variety of machining operations, such as finish milling, profile milling, slot milling, thread milling, and drill milling. They are used in a variety of industries, such as automotive, aerospace, medical equipment, and machinery. There are different types of tool milling machines, such as universal milling machine, horizontal-vertical tool milling machine, and five-axis tool milling machine. There are also CNC(computer numerical control) tool milling machines, which have computer control and enable higher accuracy and precision in machining.
